I am trying to install qjournalctl.

Before the install I did:

sudo apt-get install libxtst-dev build-essential libqt4-dev qt4-qmake cmake gcc g++ qt4-dev-tools libusb-1.0.0-dev

I downloaded the zip file and extracted it. I went into the directory and ran ./autogen.sh which did not report any errors. However when I ran make I got this. Any suggestions would be much appreciated.

It seems that qjournalctl is based on Qt5, so we need to install it:

sudo apt-get purge libqt4-dev qt4-dev-tools
sudo apt-get autoremove
sudo apt-get install qt5-default cmake gcc g++ build-essential

Then on 16.04 LTS I can compile version 0.21:

cd ~/Downloads
wget https://github.com/pentix/qjournalctl/archive/v0.21.zip
unzip v0.21.zip
cd qjournalctl-0.21/
./autogen.sh
make
./qjournalctl

I can't compile 0.3, 0.4 and master because of compilation error:

...
src/mainwindow.cpp:61:24: error: ‘nullptr’ was not declared in this scope
 message_box.critical(nullptr, "Error", "No boots have been found :n"+process.readAllStandardError());
...

I reported bug #10 upstream to github about this problem.

Note: qjournalctl compiles normally on 18.04 LTS (development version).

Note: Kudos to @N0rbert for reporting this as an issue!

Update

I've just added an option such that it should automatically try to compile for C++11 which should then fix your problem. Try downloading the new zip file (of the master branch) and try compiling it again! ;)

Workaround until I can publish a fix:

At the first sight it seems as if g++ does not automatically compile for C++11 (that's why it suggests to use the -std=c++11. Also the variable nullptr is defined when using the C++11 standard.

As a first workaround, you could execute ./autogen.sh and then edit the Makefile.
On approximately line 17 you should see something like

CXXFLAGS = -pipe -O2 -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt -Wall -W -D_REENTRANT -fPIC $(DEFINES)

Add the flag there

CXXFLAGS = -std=c++11 -pipe -O2 -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt -Wall -W -D_REENTRANT -fPIC $(DEFINES)

Then try again, running

make clean
make

It should compile fine then!
